Application filed September 28. 1917. Serial 110498 308. I

Be it known that' I, WALTER Gnmvns, a' citizen of the UnitediStates,and resident of the city of Alameda, in the: county of Alamods. and, State of California;:have'invented a certain "new and useful Fountain Pen, of j which the following is a specification.

This invention: relates to] fountain pens. Heretofore, the caps 'thatusually slip over the ink-barrels and cover thepen-pomts of fountain pens have been constructed to'contain ink-tablets, to enable the user to make 4 his 'own' ink, by means of filling the ink res- 'ervoir' with water and dissolving one of the tablets 1 therein, and threaded plugs were provided to' retain the 'inktablets within the caps. This mode of making ink for the fountain pen is particularly utilized by travelers and military persons, who find it inconvenient orimpossible .to carry along bottles of ink for replenishing the ink reservoir of the fountain pen.

The above mentioned cap construction is however. found objectionable because the ea or the threaded plug that closes up the in -tabletstherein,'being detachable, is fre-, quently lost, and the user is, thus left often without. a suppl of the ink tablets.

The princlpa object of my invention is to provide an improved fountain pen, wherein "the aforementioned disadvantages are prevented, which embodies simple, inexpensive, and improved means for retaming the ink tablets, and which the user can utilize with convenience and safety.

Other objects and advantages will hereinafter appear.

In the accompanying drawings,

Figures 1 and 2 are sectional elevations of the fountain pen, showing its parts in different positions.

Fig. 3;is a perspective view showing a detail of the fountain pen on an enlarged scale.

The fountain pen comprises an ink barrel 1 having therewithinv an ink reservoir 2 closed by an ink-feeder 3 carrying a pen 4, and a cap 5 fits over the extremity of barrel 1 to cover the pen 4 and feeder 3 and protect these parts in the usual manner. A partitioning wall 6 at the bottom of reservoir 2 separates the latter from a tapped cavity or chamber 7 formed in the rear end 8 of the barrel 1, and a cylinder or receptacle 9, for holding ink tablets, having a threaded hub 10 and a manipulatlng knurled head 11, threads into the cavlty 7. When assemblin the fountain pen, a split tapered collar 12, ig. 3, which is referably of hard rubber and flexible enough" slit 13 and tocompletely close the slit, is

slipped over and around'the cylinder 9 to a-position adjacent the head 11, and then thejcylind'er 9 is threaded into the chamber 7 to about the osition \shown in Fig. 1. The collar 12 is then premed into the cham-' her 7, between its tapped wall 14 and the cylinder 9, to the positlon shown, Figs. 1,2, .whereat the collar springs outwardly and bears against the taperingwall 15, of a counterbored portion 16, with its edge 17 lodgingagainst a ledge 18 formed by the meeting of walls 14, 15. Thereafter, the cylinder 9 may be threaded, by rotation of its head 11, into the chamber 7 to the position. shown in Fig. 2 to completely close up the chamber, but any unthreading of the cylinder 9 outwardly further than the position shown in Fig. 1

. is prevented by-the abutment of the end of its threaded. hub 10 against the edge 19 of collar 12. The receptacle 9 may be loaded with ink tablets 20 by unthreading the same to the position shown in Fig. 1 and inserting the ink tablets through an opening 21 in its wall 22 adjacent its head'll, after which the receptacle may be threaded back to the position in Fig. 2 to thereby completely close the cavity .7 and effectively retain the ink-tablets 20 therein. To extract an inktablet from the receptacle 9, the same is unthreaded to the position shown in Fig. 1 and one of the tablets is taken out therefrom through the opening 21, and then the cylinder 9 may be threaded back to normal state to close the chamber 7 and seal the opening 21.

It will be evident that the abutment of the threaded. hub 10 against the collar 12 permits unthreadin of the cylinder 9 only partially and sufficlently far to enable extracting one of the ink tablets 20 through opening 21, whereby the receptacle 9 is rendered inseparable from the barrel 1 and accidental loss of the receptacle and of the ink .tablets 20 contained therein is effectively to open wide its Variations may resorted to within the scope of the invention.

1, In a fountain pen, means for retaining ink tablets including an ink-barrel, said barrel having a cavity, means for closing said cavity adapted to be partially withdrawn for extracting ink tablets, and means to prevent complete withdrawal of said latter means to insure against loss of the latter means.

2. A fountain pen having the combination of an ink-barrel, said barrel having a cavitv. a receptacle within said cavity for the retention of ink tablets, having an opening for loading ink tablets thereinto, said receptacle adapted to be partially withdrawn for extracting the ink tablets through said opening, and means to prevent complete withdrawal of said receptacle to insure against loss thereof and of the ink tablets.

3. A fountain pen having the combination of an ink-barrel, said barrel having a cavity,

a receptacle for ink tablets within said cavity having threaded connection with said cavity and adapted to be partiallv unthreaded for extracting ink tablets, and means to prevent complete unthreading of said receptacle to insure against loss thereof and of the ink tablets.

means to prevent complete unthreading of said receptacle to insure against loss of the receptacle and of the ink tablets.

5. A fountain pen havin the combination of an ink-barrel, said arrel having a cavity, a receptacle for ink tablets within said cavity, said receptacle adapted to be partially withdrawn from said cavity for extracting ink tablets therefrom, and means to prevent complete withdrawal of said receptacle to insure against loss thereof and of the ink tablets.

(5. A fountain pen having the combination of an ink-barrel, said barrel having a cavity, a receptacle for ink tablets within said cavity, said receptacle having threaded connection with the wall of said cavity and an opening at the side thereof for loading ink tablets therethrough, said receptacle adapted to be unthreaded for extracting the ink tablets through said opening, and means to prevent complete unthreading of said receptacle to insure against loss of the receptacle tracting ink tablets therefrom, and a collar lining the walls of said cavity limiting the unthreading of said receptacle to insure against loss of the receptacle and of the ink tablets.
